WRC 2019 Agenda Item Details

Agenda Item: Agenda Item 9.1.5
Resolution(s): Resolution 764 [COM6/1] (WRC-15)
Description of work:

This agenda item relates to consideration of the technical and regulatory impacts of referencing Recommendations ITU-R M.1638-1 and ITU-R M.1849-1 in Nos. 5.447F and 5.450A of the Radio Regulations.

Comments: Footnote 5.447F relates to the band 5 250-5 350 MHz in which stations in the mobile service shall not claim protection from the radiolocation service, where constraints on the mobile service shall not be more stringent than those system characteristics and interference criteria identified in ITU-R M.1638-0 and ITU-R RS.1632-0. However Rec. M.1638-0 has been updated to M.1638-1 and the question is then whether these are significant changes that can be accepted and the footnote updated accordingly. A similar requirement relates to footnote 5.450A and the band 5 470-5 725 MHz. Furthermore, it has been suggested that there should be a new reference to Rec. ITU-R M.1849-1, and both of these would represent changes to Recommendations incorporated by reference and hence require study.
Lead Working Party(s): WP 5A
Involved Working Parties: WP 3M, WP 5B
How Visualyse products can help: Visualyse Professional can model the services and systems identified in this AI including mobile (WAS/RLAN and other), EESS (active), SRS (active) and others. It includes propagation models that can be used for terrestrial paths and Earth to space / space to Earth paths. It can include traffic modelling and aggregation effects, both co-frequency and non-co-frequency analysis using a range of methodologies including static, dynamic, area and Monte Carlo. It includes the ability to model mitigation methods including indoor attenuations and listen before transmit functionality.
How Transfinite consultants can help: We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at the ITU-R WPs. Using our in house Visualyse Professional we can quickly model a very wide range of systems, services and scenarios.
